·3D library of equipment spare parts. Spare parts of each equipment are presented to user in form of 3D, so that user is easy to retrieve and know the equipment information directly

·User can select spare parts on 3D system. As the user selected spare parts in 3D interface, the system will automatically create an order. Therefore, there is no need for user to spend much time on searching data and determining spare parts. Additionally, user and supplier can realize good communication.

·Through 3D images, users can look up records of operation, repair and maintenance of the equipment visually, so that they may fast and accurately understand the conditions of operation, repair and maintenance of the equipment.

·Supplier prepares goods and establishes spare parts library, user can inquire inventory status and order goods as required on the 3D platform, which saves purchasing time for user and makes their spare parts zero-inventory.
